Aminophylline suppository-induced acute proctitis.

A 9-yr-old boy revealed anal hemorrhage after administration of an aminophylline suppository. Proctosigmoidoscopy demonstrated edema of the rectal mucosa with hyperemia and petechiae. We performed a provocation test and obtained the diagnosis of aminophylline suppository-induced acute hemorrhagic proctitis. One should recognize that acute hemorrhagic proctitis is a rare but important side effect of aminophylline suppositories, because they are commonly used for asthmatic children.
